Welcome WanderingBrony! =D
I, like you, was nervous about expressing my fandom for MLP-FIM. As a male, it may not seem normal to like the show, but I can assure you, you are among a large community here who loves it, and you have nothing to be nervous about here!
You should check out the fluttershy fan club here: http://mlpforums.com/topic/4731-fluttershy-fan-club/
Anyways i hope you enjoy your time here, and if you have any questions feel free to ask any of us!
